CATALIZADORES PARA LA OBTENCIÓN DE HIDRÓGENO MEDIANTE REFORMADO CON VAPOR DE COMPUESTOS OXIGENADOS DERIVADOS DE BIOMASA

Abstract

The growing demand of H2 for its use as petrochemical raw material and clean fuel has boosted the development of processes for its production from alternative sources to oil, among which biomass has received special attention due to its availability and renewable nature. There is an increasing interest in the development of indirect routes for H2 production from biomass, via steam reforming of biomass-derived oxygenated compounds, and the development of catalysts that are active, selective and resistant to deactivation is the key to the viability of these processes. This paper shows the results obtained in recent works focused on H2 production by steam reforming of: i) dimethyl ether (obtained by gasification of biomass via syngas) over metallic/acid bifunctional catalysts; ii) ethanol (obtained by fermentation) over noble metals, Co and Ni supported catalysts and iii) bio-oil (obtained by fast pyrolysis) over noble metals and Ni supported catalysts.
